SVG_35kV_PLL

说明：  基于PSCAD软件，对变压器的物理模型进行建模，供大家学习(Based on PSCAD software, the physical model of transformer is modeled for everyone to learn.)

Tesseral软件的说明书，该软件主要用于石油地球物理勘探。(Tesseral software instructions, the software mainly used for oil geophysical prospecting.)

跟prony算法一样，ESPRIT（Estimation of Signal Parameters Via Rotational Invariance Techniques）也是一种参数法，它是一种基于旋转不变技术参数估计的信号处理方法，此方法可以高精度地辨识电力系统中任意组合的衰减/非衰减正弦信号的频率，相位及其幅值等信息。它不需要对信号进行同步采样。此方法把信号空间分解为信号子空间和噪声子空间，能够在较短的信号长度内准确的检测出信号中各个谐波和间谐波成分。(ESPRIT)
